Master Control is the heart of any broadcast facility. Demands for reliability, serviceability, and signal protection are essential. Equally essential, is a Master Control that can be expanded to provide for future growth as facilities migrate from analog to SD to HD. Many broadcasters look at master control as a major long-term investment.

The QMC-2 master control switcher has been designed to meet the current Master Control needs with the capacity to meet future needs. The QMC-2 platform provides a cost-effective solution for facilities converting to SD and HD. The hardware platform runs solid field-proven software to form a foundation that meets the latest playout and branding needs. Other major features the platform includes are bypass and emergency inputs, hot-swappable hardware, and redundant power supplies. Combined, these features create a reliable system for 24/7 year round programming.

Evertz® Integrated Solution • The QMC-2 offers a unique approach to Master Control with SD and HD channels with a number of options and a broad selection of configurable control panels. QMC-2 systems can be assembled to meet any need and size. A QMC-2 system is comprised of an upstream router, feeding a number of processing channels. This architecture allows systems to scale from a single channel up to a complex multi-channel installation with minimal effort. The feature rich QMC-2 can be easily controlled under automation or manual control. The QMC-2 intelligent LCD pushbutton control panels give operators high flexibility in panel layout and user-friendly functionality. The QMC-2 also integrates seamlessly with the Evertz multi-viewer MVP product line, which allows customers to have a complete "turn key" master control solution.

The QMC-2 Platform

QMC-2 is designed to support both high definition and standard definition video formats. The formats include: 525i/59.94, 625i/50, 720p/59.94, 720p/50, 1080i/59.94, and 1080i/50. Each QMC-2 processes a complete Program and Preset path, which provides a Program output and a full "look-a-head" Preview of the next transition. A third Emergency input allows users to quickly go to a safe feed in case of emergency. The QMC-2 also provides an auxiliary output for "Clean feeds". For audio, the QMC-2 provides support for 16 channels of embedded audio on the Program, Preset, and Emergency inputs. It also provides for discrete AES inputs and AES outputs. The QMC-2 frame is 3RU with dual power supplies. The frame has built-in bypass relays, which provide maximum protection for the Program and Clean feed in cases of failure. The frame has been designed to allow for two HD or SD QMC-2 channels to operate independently of each other.

QMC Control

Manual Control • The QMC-2 system was designed for ease of use in live and automated environments. The range of QMC-2 control panels has been optimized for size and ease of use in single and multi-channel playout applications. All QMC panels use 10 character LCD buttons, providing a dynamic control environment. Every button is user-configurable, which enables panel layouts that are operator friendly. The panel layout provides a menu system, which exposes the full capability of the QMC-2 to the operator. The control panels start with the 1RU QMC-CP-1000E version to the full size QMC-DCP desktop control panel.

Automated Control • Each QMC-2 channel can connect to the leading automation systems through a dedicated serial port located on every channel. This gives low latency and maximum protection against on-air problems. Crosspoint control of upstream routers is handled directly by the QMC-2 so only a single port on the automation system is required for each active channel.

Upstream Router Control • Each QMC-2 channel can control any size of router matrix ranging from 12 inputs to 256 inputs. For "turn key" environments, the QMC-2 integrates seamlessly with the Evertz Topaz, Xenon, and EQX router product lines. For existing routing infrastructures, the QMC-2 has support for the leading router vendors.

Features

Video/Audio Transitions • The standard QMC-2 configuration includes a number of video & audio transitions such as V-Fades, Mixes, and Split audio/video as well as optional wipe transitions. These transitions can be controlled via the QMC-2 control panel or the automation system and can be customized at any time. Audio, Dolby, & Voice-overs • The QMC-2 has powerful and flexible audio capabilities. With a standard 16 channels of embedded audio, it is easy to integrate into any station. Audio level adjustments may be made from the panel at any time and stored on a source-by-source basis. Internal audio shufflers allow routing from any input to any output. Built-in sample rate converters allow any mix of 44.1kHz and 48kHz sources to be used and silently switched on-air. Optional Dolby-E/AC-3™ Decoders and Dolby-E™ Encoders allow the QMC-2 to handle Dolby 5.1 programming. The QMC-2 can perform two independent stereo voice-overs, each map-able to any or all output channels. Full "pre-hear" allows level and voice-over ratio to be set prior to going on-air. Voice-overs can be taken to air combined with another transition or independently.

Keyers • Up to three external key layers may be fitted to all QMC-2 models. One keyer is standard while two additional keyers can be optionally added. They have a full range of user adjustments stored and recalled on a source-by-source basis. Keyers may be taken on and off air with other key levels or independently, and order/priority can be set. Branding • The internal Logo store for the QMC-2 is optional. It allows a station, channel or program identification to be keyed over the Program output. Logos can be transitioned onto the Program output at any time using any of the standard video transitions. Multiple logos are stored within the QMC and can be called up from an automation system or from the control panel. The addition of the QMG option will allow for enhanced branding that include: multi-layered static/animated media, audio clips, time/temperature logos, text headliners, and text crawls. DVE • The two-channel 2D DVE option provides live and dynamic visual effects, such as picture sizing and positioning, and is fully integrated within the QMC-2. The DVE is fully assignable within the video-processing path of the QMC-2. The DVE may be controlled manually or from the automation system and is independent of the key and logo (bug) layers.

QMG - Enhanced Branding Solution for Master Control

As the traditional Master Control environment evolves, demands on branding have increased. The QMG option enhances the on-air branding capabilities of the QMC-2. It adds a complete logo and media insertion package to the Master Control path, which will simultaneously key an additional 16 layers of static or animated "bugs" over the HD or SD video signal. It also offers the options for the use of audio chimes/snipes, text teasers, and dynamic text crawls. The QMG occupies one slot in the QMC-2 3RU frame.

The QMG has been designed to manage and store multiple static/animated logos and audio clips. The size of each logo is variable and range from 1/25th to full screen. Various media formats (such as Tiffs, TGA, Bitmaps, and Wave files) can be imported into the Evertz® media software and transferred to the QMG via Ethernet. The position of the logo, fade rates, clip association and animation rates can be controlled through the various QMC control panels.

Media is stored into flash memory that can be quickly recalled by the various QMC-2 control panels or automation. With the removable compact flash option you can have access to up to 16GB of on-line media storage space. The Network Attached Storage option utilizes the Gigabit Ethernet of the QMG to connect a media server device. This allows the QMG to access virtually unlimited archived media storage. This approach in addition to the suite simplifies the workflow within the Master Control environment.

The QMG can be used in two modes: Key/Fill or Program/Preview. In the Key/Fill mode, the QMG generates a Key and Fill signal that is connected to the QMC-2. In the Program/Preview mode, the QMG is downstream of the QMC-2. The on-board preview allows users to cue their logos for position and content verification prior to going on-air. As well, the Program/Preview mode allows for an optional two-channel 2D DVE to be inserted in the processing path to provide two programs over a background effect.
